Cygnus Performance has been a leader in Subaru suspension for years. After stocking nearly every available brand of swaybars we can say these are no question the highest quality, best designed bars that we've ever seen. They are 100% designed and built in Australia, while almost all other options are now manufactured in China or Korea. They have several impressive features which set them apart from the competition. They are made of 100% high quality Australian spring steel. All bars individually checked on a jig to ensure there is no more than plus or minus .5mm twist or distortion in the bar, this makes a perfect fit everytime, every bar. The bushing side locaters are fitted to the bar before powder coat and screw locked in place and then powder coating is completed over the top to ensure not being able to come lose. Powder coating is a three part process, 1/ zinc primer 2/ epoxy sealer 3/ blue powder coat which is formulated to stretch or flow on impact not chip easily. This avoids a break in the surface from road rocks and stones etc.. This unique process adds up to 1 mm to the bar diameter and the mounting bushings are all specifically sized to accommodate that increase to avoid over compression when assembled in the vehicle. For example a 22mm bar will have a D bushing of 23mm. If you do the research on all options available you'll find that no other swaybars even come close to the quality of these. If you want the best swaybars that money can buy, you want Super Pro.
